In 1513 Robert Scorer was the lessee. His very interesting will, made on the 9th of November in that year, left to his brother Richard the guardianship of his children, and also "all and as many gunstones of iron as be now redy made as well at London as at my fferme of Parok or any other place in Sussex, which I will shall be delivered to him by myn executrix....................

In 1518 Richard Warner mortgaged or leased the manor of Parrock to John Carill, including "a parcel of land called the Weke with a myll builded upon the same grounde called an yron myll, and all the yronworks builded upon the same p'cell of land ; that is to say, a ffurnes, a fyner and a hamer with all many of instrumentes thereunto belongyng." It still belonged to Warner in 1525.

In 1564 William Saunders, Knight, was in peaceable possession, and in 1570 left the iron mill to his son Nicholas. In 1574 the furnace and forge were worked by George Bullen, of Hartfield, for Lord Buckhurst, probably leased from the Saunders family. In 1590 the works were sold to another Nicholas, who again sold them in 1593 to William Garway. They passed to John Garwav in 1600.
